How about random kor'kron rogueish guards sneak at you if you are busy being afk, at a mailbox, or just strolling through the drag. They take you with an animation of you in their arms getting carried away. They would have generic you are getting arrested talk something of that such. They take you behind a building and kill you. Lol it would happen say 1 player per every 50 and every few hours or so. Give you a real sense of danger. It would be a good way to take care of those pesky gold sellers or instill fear into the level 40s on their shiny new kodo.
I didn't find the right solution from the Internet.
